Installing double interior doors: the details of the process
Today, you will learn the special features of installing double doors, which tools are useful for installation. We will also tell you about the intricacies of this process.
If you decide to acquire such a practical piece of furniture, as a double interior door, then you just need to know some of its features and subtleties.
This species differs in several categories:- By the principle of action: sliding (see. Doing sliding interior doors with their own hands: installation technology) and hinged.
- Composition (production material): wooden, made of MDF, plastic, glass, aluminum.
- By type of construction: massive, framed deaf, framed glazed.
Installing double doors: where to start
First of all, you need to get rid of the old, its boxes and cashing. We do this with the help of an ax and a hammer or a bent line with a nail puller.
Note! If you want to save the box to be dismantled, first carefully remove the trim. Then clean the opening from the cement and foam. After that, unscrew the screws from the box beam with a screwdriver, or cut the nails with a grinder.
Next, remove the remnants of the plaster punch. If it keeps well and has a flat surface, then it will be enough to remove the frozen foam with a stationery knife.
Measurement and preparation of the opening under the double interior door
The next stage: installation of double interior doors. First of all, think about how to install: in the form of a swing or sliding design.
Each type of opening has its own characteristics:
- Sliding will be optimal in a small room. They save space. In order for the doors to disperse, you need to buy a special design for hanging and sliding doors.
Note! If you build a drywall box on both sides of the opening (see How to make a door opening from drywall), then when you open the door will hide there and they will not be visible. But at the same time, the effective area will be reduced due to the box dimensions.
- Устанaboutвка в качестве распашных является самым распрaboutстраненным вариантaboutм. This way of opening the canvas improves noise insulation compared to the sliding design. But it takes more space that can be used to place furniture near the opening. Swing interior doors are most often installed in spacious rooms.
After selecting the structural features of the opening, you need to take measurements of your opening and, if necessary, reduce or enlarge it. At the same time, keep in mind that the width of the opening must be more than 90 by 110 mm.
The calculation of the width of the required opening for swing doors is made according to the formula:
- Shpr = 2 * (Tdk + 3 + Shdp) +4, where
- Шпр – ширина двернaboutгabout прaboutема;
- TDK - the thickness of the box beam;
- Shdp - the width of the door leaf.

Now you can proceed to the preparation of the opening. We make expansion with the help of a puncher, grinder or chainsaw. It all depends on the material of the walls. We narrow the doorway with plaster, putty or lumber (for wooden walls).

Installing double doors: assemble the door frame
Before you start collecting the box for a double door, you need to adjust the box beam to the required dimensions.

To do this, use the formula:
- Shvk = 2 * (Shd + 3) +4, where
- Shvk - width of the inner side of the box;
- Shd - the width of the door.
You need this data before installing a double interior door:
- After marking we cut off the box beam at an angle of 45about. The most convenient way to do this is a face saw. If it is not there, then use a small-toothed hacksaw and miter box.
- Next, cut the hinges (see hinges for interior doors) in the vertical part of the box and the door. We do it with the help of a milling cutter or a hammer with a chisel. If there is no desire or time for this operation, then when choosing loops, pay attention to the overhead butterfly loops. They do not need to embed.
- The final stage in the assembly of the box - the connection of all its parts. First, we connect the parts and twist them with three screws.
Note! To prevent the wood from cracking, you need to make a hole before screwing in the screw. When the screw thickness is 3.5 mm, the drill bit should be 2.5 mm in diameter.

We continue to talk about how to install it. We have come to a very significant process - the installation of the box. It is on the accuracy of its implementation depends on the correct operation of the canvas.
For proper installation of the box is best to use the construction level with three eyes. You will also need wooden wedges for fixing the box in the opening.

Sequencing:
- We insert the assembled box into the opening and, using the level, align it. Watch not only for compliance with the vertical, but also to ensure that the edges of the beam do not protrude beyond the limits of the opening.
- After setting we fix the box with wedges.

- Remove the box and drill holes in the wall under the cork.

Installation involves the following actions:
- We fasten rollers to cloths.
- We plan at what height the rail guide will be mounted.
- With the help of the level we outline the line and fasten a block on it to the wall 40-50 mm thick.
- Install the rail on the bar and hang the door on it.
- Close the guide strip with a decorative strip in the color of the door leaf.
Now you know how to install an interior double door. And as you can see, there is nothing complicated about it.
